CULTIVATOR.

Specification of Letters Patent.

Patented Mar. 16, 1915.

Application filed April as, 1914. Serial No. 834,444.

To all whom it may concern:

Be it known that I, WALTER M. REYNOLDS, a citizen of the United States,residing at Hattiesburg, in the county of Forest and State ofMississippi, have invented a new and useful Cultivator, of which thefollowing is a specification.

This invention relates to cultivators, one of its objects being toprovide means whereby the structure can be converted readily from atoothed cultivator to a disk cultivator, the shank employed for holdinga cultivator blade or shovel being also employed for connecting a diskto the cultivator structure.

A further object is to provide improved means for connecting the soilengaging elements adjustably to the main structure of the cultivator.

With the foregoing and other objects 1n view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without de arting from the spirit of theinvention.

11 the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :-F igure 1 is a plan view of a cultivator having disksoil engaging elements. Fig. 2 is a central vertical longitudinalsection on line AB Fig. 1.

Referring to the figures by characters of reference 1 designatesparallel central beams preferably formed of one piece or strip of metalfolded at its center, as at 2, the terminals of said strip being ofisettoward each other, as at 3 so as to receive between them and be boltedor otherwise secured to a clevis 4. Secured to the portion 2 is a bowedframe member 5 merging into forwardly converging side members 6, thefront ends or terminals of which are offset inwardly as at 7 so as toengage the sides of the offsgt portions 3 and to be secured theretachiiig' he oii'set portion 3 to the clevis 4.

A block 9 is interposed between the central beams 1 and has anupstanding car 10 to the sides of which are secured upwardly andrearwardly converging handles 11 which may be provided with a crossbrace 12. This brace can be formed of metal and can be made integralwith standards 13 secured in any suitable manner to the bowed portion 5of the frame.

Extending above and below the beams 1 and the side portions 6 are upperand lower arms 14, the upper arms lapping at their inner ends and thelower arms also lapping at their inner ends, as shown particularly inFig. 2, these lapping portions having a combined pivot and clamping bolt15 extended through them and between the beams 1. By loosening the boltthe arms 14 can be moved to any desired positions upon the beams 1 andside portions 6 and can be adjusted angularly relative to each otherafter which, by tightening the bolt 15, the parts can be held againstmovement relative to each other. Additional clamping bolts 16 can beextended through the upper and lower arms 14 beyond the outer sides ofthe portions 6 and by tightening these bolts 16 the arms 14 can becaused to bind upon the side portions 6, thus to assist the bolt 15 inholding the arms 14 against relative movement.

If desired, and as shown particularly in Fig. 2, a wheel 17 can belocated between the front portions of the beams 1, this wheel beingjournaled on a stud 18 extending laterally from a plate 19. Arms 20extend upwardly from the plate and are provided with longitudinal slots21 for the reception of clamping bolts 22 extending through one of thebeams 1. By means of these bolts and the slots, the wheel 17 can beadjusted upwardly or downwardly relative to the beams 1, thus toregulate the depth of the cut produced by the soil engaging deviceshereinafter described.

The side portions 6 of the main structure are adapted to carry a desirednumber of holding devices whereby soil engaging devices may be securedin place. The holding devices to be carried by these side members 6 areconstructed as shown in Fig. 5. Each of these holding devices includes ablock 23 having a broad flat surface 24 designed to bear against theouter side of the portion 6 and a substantially vertical groove 25 inits outer portion. The upper and lower ends of the block are engaged bythe upper and lower arms 27 of a U-shaped tie device 28 which straddlesthe side portion 6. Openings 29 are formed in the arms 27 and areadapted to register with the groove 25 so as thus to receive a shank 3Oresting in the groove 25. A tapered holding pin 31 is insertible intoopenings 32 formed in the arms 27, this pin being adapted to enter backof the side portion 6 so that, when the pin is driven downwardly, itwill act as a wedge and bind the block 23 tightly upon the outer surfaceof the side portion 6 and at the same time cause the forward portions ofthe walls of openings 29 to clamp upon the shank 30 and hold it securelywithin the groove 25.

The arms 14 are provided with holders of a different pattern and whichhave been illustrated in Fig. 6. Each of these holders includes a block33 having a substantially vertical groove 34 in one face while heads 35are formed at the upper and lower ends of the blocks and adapted to lapthe upper and lower faces respectively of the upper and lower arms 14. Atongue 36 extends rearwardly from the block and into the space betweenthe arms 14. A loop 37 formed preferably of sheet metal extends aroundthe block 34 and between the heads 35, this loop being extended betweenthe arms 14 and projecting rearwardly therebeyond. A wedging pin 38 isadapted to be inserted into the rearwardly projecting portion of theloop and a standard 30 is adapted to be placed between the forwardlyextending portion of the loop and the block 33, this standard or shank30 resting in the groove 34. It is to be understood that any desirednumber of these holders may be mounted on the arms 14.

For the purpose of holding a shank or standard between the beams 1,holding means such as shown particularly in Figs. 3 and 4 is employed.This holding means includes opposed blocks 39 each of which has atransverse groove in its outer face for the reception of one of thebeams 1. Substantially vertical grooves 41 are formed within the innerfaces of the blocks and are designed to register, these grooves beingdesigned to receive a shank or standard 30. A bolt 42 is extendedtransversely through the beams 1 close to the blocks 39, as shown inFig. 1 and by tightening this bolt 42, the blocks can be caused to bindtightly upon a shank 30 inserted between them.

As shown in the drawings, each shank or standard 30 may be provided witha soil engaging element such as a disk 49.

Obviously the relative positions of the shanks or standards can bevaried at will in order that the desired action upon the soil may behad. The blocks 39 can be adjusted either up to the front or to the rearportions of the beams 1, the arms 14 can be adjusted angularly about thebolt 15, the holders 33 can be adjusted toward or from each other so asto bring the shanks to any desired distances apart, and the holders 24can be adjusted to any desired positions along the side portions 6 ofthe frame. Furthermore if desired, the shanks 30 can be inverted so thatthe points 43 thereof can be used as harrow teeth.

What is claimed is 1. A cultivator including parallel central beams,rearwardly diverging side members merging at their rear ends into anarcuate portion, said arcuate portion being connected to the rear endsof the central beams and said side portions being connected at theirfront ends to the front ends of the central beams, oppositely extendingpairs of arms, the beams and side portions being extended between thearms of the pairs, said pairs being pivotally connected, means forbinding the arms upon the beams and side portions of the frame, and soilengaging devices carried by said side portions, arms and beams.
